Fan shaft on belt driven model is turned, ground and polished and receives a high quality rust preventative coating prior to shipment.

Arrangement 9 comes standard with belt guard and two support legs for shipping and mounting support.

BENEFITS:

Benefits of Model "SQAF" Airfoil Blowers are:

INCREASED EFFICIENCY: Airfoil wheels provide the highest efficiency
of all centrifugal fan designs. The static efficiency of an airfoil wheel versus
a backward inclined wheel can easily exceed 10%. This benefit results in lower brake
horsepower consumption and a reduction in sound levels of 2-6 dBA. Less expensive
to operate and quieter.

MULTIPLE WHEEL SELECTIONS: Each size and class is available with
two airfoil wheel types and multiple widths from 50% to 100%, in 5% increments,
to deliver the exact performance you need with a direct driven blower. Complete
design flexibility.

RUGGED CONSTRUCTION: Housings are heavy gauge steel and are continuously
welded to prevent leakage. Fan bases are 7 and 10 gauge steel with internal bracing
to prevent pulsation at all conditions. Less field problems.

EASE OF MAINTENANCE: Replacing a wheel or motor, or shaft and bearings
on belt driven models, is easily accomplished without disturbing the inlet and/or
discharge connections. Minimizes extended down time.

QUALITY COMPONENTS: Belt driven model has self-aligning, cast iron,
grease lubricated, pillow block bearings sized for a minimum 150,000 hours average
life. Fan shaft is turned, ground and polished and is coated with a high quality
rust preventative before shipment. Long dependable service.
